The autobuilders are completely unrelated to the defconfigs.

We have two completely distinct CI mechanisms:

 (1) Gitlab CI. This one does the kind of traditional CI that most
     projects have. In the case of Buildroot, it does build the defconfigs
     and runs the runtime tests on a regular basis.

 (2) Autobuilders. These generate random configurations, and build
     those random configurations. We have a number of machines (about
     5-6 machines) that do this 24/7 and report the results at
     http://autobuild.buildroot.org. This gives a much wider testing
     coverage than building defconfigs, as our defconfigs are almost all
     minimal.

So, when I say "autobuilders", I'm referring to (2) above. And I don't
get why this sys/io.h doesn't occur in the autobuilders.

Best regards,

Thomas
